"Be it knownthat'L'ErTA'H. RYON; acui- "Aenof the lUnited State's, residing at Wal thanninthe county of lilijd dlesexfand State of Massachusetts, have invented a new and useful Weft-Carrier-l lolding Device for Stationary 'l'fagaaines, of which the following is a specification; H

1 V This invention relates to a weft carrier magazine ofthe stationary type in which thewetcarriers are placed in a series of vertiealcompartments from which they are successively removed as required by the op-. eration of'the loom. The'weft carriers in these vertical compartments are found capable oftwistingor turning movements while in storage, frequently resulting in entangling the weft ends, with consequent breakage thereof upontransferto the active shut-- In my prior Patent No. 1,467-,653,issued Sept; 11, 1923, I have shown devices for yieldinglyengaging the butts of the weftcarriers to pre'vent'such angular movement thereof and means for automatically with drawingthe holding device of a given cornpartment frompperative position upon in dication' of weft exhaustion tobe replenished from that particular compartment.

Itis on'eobject of my present invention to provide means for simultaneously withdrawing all of the holding devices from operative position whenthe'operator desires to replenish the magazine-compartments.

My invention further contemplatesthe provision of means for automatically restoring the holding devices tooperative positionafter such withdrawal.

In the presentembodiment of myinven' tion I provide for the operation of the automatic restoring mechanism on the occasion of the next subsequent weft carrier transfer, thus insuring the return of the holding devices to operative position within a negligibly short period after the filling of themagazine.

My invention further relates toarrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

,A preferrecl forni of the invention is shown'in the drawings, in which- M .Fig. 1 is a side elevation of a weft carrier magazine embodying my improvements;

2 is a partial. sectional plan view thereof, taken along the line2.2 iILFig'Jl; ;'Fig. 3 is a partial sectional front elevataken along line. 3-3 in Fig. 2;

.Fig. t is a, detail sectional view taken along the line lii in Fig. 2; and v Fig.6 is a perspective v1ew of one of the holding. devices.

Referring tothe drawings, I have shown afiveft carrier magazine of a, usual comv inercial type and havinga magazine frame 10 with ribs orprojections 11 on its inner face, dividing the, magazine intoa series of vertical compartments 12 within which tlieweft carriers are stored. I have v also shown vertically moving, release menihers or bars 13; looking plungers 14 for said bars, and liftinglevers 15 (Fig. 3) mounted on a cross shaft 16 1) and adapted to selectively engage and. move the bars 13. The shaft 16' is movable both axially and an; gularlyto engage andlift a selected release member or bar l3,upon indication of exhaustion of-a weft carrier corresponding to the compartment associated with said bar. The bar 13. after being raised by its arm "15, is held in raised position by its plunger 14 until the indicated shuttle returns to transfer position. lhe bar 13 is then depressed by the action of an arm or plate 17 (Fig. 3) mounted on a shaft 18 connected foif movement by actuating devices not shown. A. shuttle feeler 20 is connected to the shaft 18 through an adjustable link 21 and an arm 22 (Fig. 2). For a more complete description of the construction and operation of these usual parts of this type of weft carrier magazine, reference is madeto my prior patent above mentioned.

7 For restraining or preventing turning movements of the weft carriers in the compartments 12, I provide each compartment with a vertically extended holding device 25 whicln in its preferred form, comprises a blade or plate slidably mounted in slotted guiding project-ions 26 and each having cam portions 27 and 28 which engage projections 31 and 32 on the magazine frame as the blade or devicemoves down, such movement being assisted by a spring for each blade.

Each device, 25 is provided with an out wardly projecting portion 33 (Flg. 5)" having an offset flange or lug 34 at the lower end thereof. The lugs 84 are positioned 'for engagement by the upper ends' of the release bars 13 asthey move upwardly to release the Weft carriersj'upon indication of I W iist qn, by such engageme t each dev1ce25i f1's wwithdrawn fromoperatlve 7 corresponding ,wef t carrier 1s W position-as a released. p h My present invention relates particularly to the provisionof a slideeO inountedonthe irame lQ and having a pluralityof \l shaped notches or learn 'surfaces 41, formed in the upper-ledge thereof. The pla't'e iO is prefer 'ablyflsecured in position by caps or' cover plates 4; 2ia t therends thereof andby ascrew 4:3 fektendingvthrough, a slotqett. near the center thereof. The slideAO is also bent at I right angles at 45: to provide 1 a convenient handle. and i the 5 opposite el1d lS of, semicircular" form as indicatedat i46. The normal l running position of zthe slide is atfthe extreme right or front of its pathaoftravel,

devices 25; a

When-the operator to .replenish the holding the deices 25 "by the a ction of the .a cam surfaces ll/ All of'the devices 25- are thus held in Withdrawn positionwhile the "magazine is being 'filled "by the; operator;

Having completed the: filling of the magazine, the operator is presumed to restore the slide to-the position shown -in'iFig. 1 thus releasing the devices 25 to engage the weft carriers, r I

Inthe event that theoperator occasionally forgets to restore the slide 40 to inoperative position, I have provided an 'armV-50o'secured to the end of the shaft 18 and having an oliset end 51 with upper and lower cam surfaces." As the'arm 50 is moved downward and thereafter upward at the transfer of the nextsucceeding Weft carrier, one of the cam surfaces on the end-51 will engagethe monly intervening is so short that entanglemagazine having a plurality o magazinehavinga plurality of ye compartments, me ns 0 render" compartments, manualmeans to-render p at, In -a ]oom,'1n comb nation, a stationary gularmovement of theweft carrie compartments, means tojrenderiall f ea d v 5; a In a loom, incombinatio ,gularmovement of the; weaearriers tive upon "the next succeeding weft means to 'movesaidslide in thelopposite 'positionliw p 7.
